Fix hex32_arg parsing for short reads (here 7 hex digits instead of the expected 8), shift result only on successful input parsing.

• before the patch

  $ echo "mpls 0000123" > /proc/net/pktgen/lo@0 $ grep mpls /proc/net/pktgen/lo@0 mpls: 00001230 Result: OK: mpls=00001230

• with patch applied

  $ echo "mpls 0000123" > /proc/net/pktgen/lo@0 $ grep mpls /proc/net/pktgen/lo@0 mpls: 00000123 Result: OK: mpls=00000123
